Design of Elastomeric Shock Absorbers with a “Soft” Stiffness Characteristics of Type “Force-Settlement”

In the design of Vibration isolator is often required ensure a reduction (or increase) the value of frequency ηr, that is connected with the ability to calculate the stiffness characteristics of elastomeric Vibration isolator in the low final and medium final deformations. A similar problem arises in the design and calculation equifrequent rubber-metal compensating devices, which find application in various fields of engineering and construction industries, effectively replacing the hydro- pneumatic - spring compensating device, working under axial stress-strain. In this case, the stiffness characteristic of “force – settlement” P = P (Δ), even for small final deformations, will be non-linear (or piecewise linear). In this title proposed a method for determination of rigidity dependence "Force - Settlement" for shock-absorbing elements with absolutely rigid moving (parallel to the vertical axis z) vertical side stops being under pressure, and it lets take into account low compressibility of material of rubber layers. Receiving solutions can be used to find the dependence „force - settlement” cylindrical shock absorbers, as well as in projecting such shock absorbers. You can to design a shock absorber with a given non-linear („hard” or „soft”) stiffness characteristics
